STEAM AND WATER HEATING APPARATUS.

Specification of Letters Patent.

Patented Dec. 31, 1907'.

Application filed June 18, 1904. Serial Nox 213,064.

To all whom it may concern.'

Be it known that I, EUGENE S. MANNY, a subject of the King of GreatBritain, residing at the city and District of Montreal, in the Provinceof Quebec, Canada, have invented certain new and useful Improvements inSteam and vWater Heating Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,suoli as 'will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to new and useful improvements in hot waterheating apparatus, and is intended to be used in connection with somesuitable source of steam supply, which steam is to be used for heatingwater, the water to be conducted by suitable pipes to the place orcompartment to be heated.

The object of the invention is to produce an apparatus comprising aplurality of water heating compartments, which are connected in parallelto suitable water supply mains or conduits in such manner that waterfrom such mains may be admitted to one or all of such heatingcompartments, wherein the water may be heated, or reheated, to raise thetemperature thereof to the proper degree for heating compartments of abuilding.

In large buildings, such as hospitals, asylums, &c., it is desirable toregulate the supply of heat according to the weather, and, where but oneheating apparatus is used, great difliculty has been experienced insecuring the nice adjustment of heat which is so essential to therequirements for such buildings. To overcome difliculties heretoforeencountered, the apparatus herewith illustrated and described has beenprovided, in which a series of heating compartments are provided for thewater, each of such compartments being connected with a water supplymain and conduit, so that all of the compartments may be used whendesired, and steam is admitted to the interior of the compartments,passing through steam pipes therein so as to heat water passingthrough.Means are also provided so that any one or more of the heatingcompartments may be cut out of the general system, thereby reducing theradiating or heat producing surface, and to such extent decreasing thesupply of heat from the water of the mains to the buildm0:

`iln the drawings, in which similar numerals of reference indicatecorresponding parts in all the views, Figure 1 is an elevational viewillustrating the general arrangement of the heating compartments, someparts of said compartments being removed and one compartment being shownin section on the line 4-4 of Fig. 2. Fig. 2 is an end elevational viewshown partly broken away and partly in section, for the purpose ofbetter illustrating details of construction thereof.

Referring to the drawings, 1, 2, 3 and 4 denote the several heatingcompartments of the system. Leading to the compartments 1 to 4inclusive, in detail as hereinafter shown, is a steam supply pipe 5,which may connect with any suitable source of supplyfor the purpose ofheating the compartments and water passing therethrough.

A feature 'of this invention is the manner of forming the heatingcompartments, which, as will be noted in Fig. 2, are provided with steamtubes 6, extending longitudinally thereof, said tubes being supported attheir ends in the perforated end. walls 7, and so connected therewith asto prevent leakage of water between the connection of said tubes withsaid walls, thereby rendering the water heating compartments 1 to 4formed between the end walls within the shell 9, perfectly water tight.

Connected with iianges 10 of the heating compartments, are collars 11(see Fig. 2) which are provided with the flanges 12 and 13, the flanges12 being bolted to the flanges 10, and securing thereto the walls 7, andthe heads 14 being bolted to the iianges 13 of such collars, wherebythere are formed steam chambers 15 between the walls 7 and said heads.Tapping the collars 11 are steam pipes 16 and 17, which are designed toserve respectively as steam inlet and steam outlet conduits therefor.

Valves 18 are provided in the pipes 16, and similar valves 19 areprovided in the pipes 17 whereby the supply of steam may be cut off fromone or more of the said compartments, which still serve as parts of theconduit for the general circulation of water, and as the quantity ofwater is not decreased by closing such valves, it will be evident thatwith the same supply the temperature will decrease when such valves 17and 19 are closed in part of the series.

The supply main 20, supported on a standard 20a, extends below theheating compartments 1, 2, 3 and 4, and is connected therewith by meansof the short leaders 21,

iii which are placed valves 22. The leaders 21 communicate with theinterior of the compartments, and when valves 22 are open, water willpass from the supply main into suchv compartments, wherein it will beheated by means of the steam in chambers 15 and tubes 6, after whichsuch water will pass lout through the short connecting conduits 23 tothe hot water supply pipe 24 which leads to the compartments to beheated. In the conduits 23 are placed valves 25 adapted, with the valves22, to cut out any of said compartments from the circulation system whendesired. As each compartment may be cut out in this manner it is evidentthat one or more of such compartments may be taken out of thecirculation system.

The systeml of circulation may include pumps for forcing the water toany required distance from the heating apparatus herewith sliown, butsuch pumps may be, and have been, placed in any convenient part of thegeneral system, and are so well known as not to require illustrationherein.

Assuming the main or return pipe 20 to be connected with the generalcirculation system of a hot water heating apparatus, it is evident thatwater will rise through the leaders 21 into the compartments l, 2, 3 and4, when the valves 22 are open. lIhe water i will be heated in suchcompartments and pass out through the short conduits 23 to the hot watersupply pipe 24, and thence to the building to be heated. When the fullcapacity of the apparatus is needed, the valves are all left open, and amaximum vsupply of heat and of water will flow through the apparatus.When less heat is required, one or more pair of the valves 18 and 19 maybe closed, and steam thereby cut oil from one or more of the heatingcompartments, leaving the same volume of water to be heated. Vhen thevolume of water to be heated is to be reduced, one or more pair ofvalves 22 and 25 may be closed, thereby lessening the supply of water tothe heating compartment.

' While I have shown in the accompanying drawings the preferred form ofmy invention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and I therefore reserve the right to make all such modifications as areincluded within the scope of the each end, a perforated end wall heldbetween` thellange of said casing and the flange on one end of saidcollar by a common securing means, and a head detachably secured to theflange on the other end of said collar, tubes supported in said endwalls and establishing communication between said steam chambers, meansfor admitting steam to one of said steam chambers, means for dischargingthe steam from the other of said chambers,

means for admitting water from one of said mains to the intertubularspace, and means for discharging it into the other of said mains.

2. In a hot water heater, the combination i of a cylindrical casingprovided with op osite lateral openings and having an annu ar flange atone end, a steam chamber at each end of said casing, one of said steamchambers comprising a collar provided with a lateral opening and havingan annular flange at each end, a perforated end wall held between theflange on said casing and the flange on one end of said collar by acommon securing means, and a head detachably secured to the flange onthe other end of said collar, tubes extending through the perforationsin said end wall and establishing communication between said steamchambers, means for admitting steam through the opening in said collarinto the corresponding steam chamber, means for discharging the steamfron the other of said steam chambers, means for admitting water throughthe opening in one side of said casing, and means for discharging itthrough the opening on the opposite side.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
